Two years ago today, we packed up 88 years of history and moved out of our old location… and somehow our “new” location is already turning 2?! 😳🎈

So if you still haven’t visited the “new” spot yet… respectfully… you need to party more. 😂

We’re now easier to get to from all the major freeways, have WAY better parking, and we’re right by Costco in S**O, making party supply runs a whole lot easier. 🛍️🎉

This year marks our 90th year in business, and this move was our FOURTH (and hopefully final 😅) move in all that time. Thank you for supporting us through every chapter, every location, and every celebration along the way. ❤️

Swipe to see the empty old space vs. the place we now call home. What a difference two years makes. 🥹

Behind every emotionally detached daughter with a killer stare is a proud mother saying, ‘That’s my girl.’

Happy Mother’s Day to the Morticias raising little Wednesdays everywhere. 🕸️🖤
